The Osaki 4D+3D Bravo Duo Flex is a next-generation massage chair built for a personalized, full-body experience - a dual roller system, walking-motion leg stretch, and a flexible SL-Track that adapts to your body as you recline.
Its dual massage system pairs an upper 4D mechanism, which offers a range of techniques and intensity levels across the back, with a lower 3D mechanism that delivers deep, consistent pressure to the glutes and upper hamstrings so relief reaches your entire back in one session. A self-adaptive, flexible SL-Track extends as the chair reclines, keeping roller contact from the neck and shoulders down through the full spine, hips, and thighs. The Bravo Duo Flex doesn't stop at the back, either: its walking-technology mechanism replicates a natural walking motion to gently stretch the lower back, glutes, hamstrings, and knees, something few chairs at this price attempt. A computer body scan maps your unique shape before each session, and intelligent voice control lets you run the whole thing hands-free.
Round out the experience with 38 air cells compressing the shoulders, arms, calves, and feet, lumbar and calf heating pads for soothing warmth, and specialized reflexology foot rollers working key pressure points. Choose from 22 auto programs or 6 manual massage modes on the intuitive touchscreen controller, settle into a 2-stage zero-gravity recline that needs just 4 inches of wall clearance, and finish the session with wireless phone charging, Bluetooth speakers, and shifting LED ambient lighting - all controllable from the convenient side panel or the automatic footrest, which extends up to 6" to fit your height.

The best Company we have ever dealt with.
Had a small late shipping issue, but they completely made it right with us. Quality of products are amazingly strong and durable. We definitely will do business with them again.
The IBIS wheelchair to car lift was a game changer for us. My husband has been in a wheelchair for more than 40 years and we have never seen anything like this in the US and had no idea such a lift exist existed.
My guy is hemiplegic and usually able to stand pivot into the car but he broke his femur in November 2025 and had to be non-weight bearing for 3 months. He lost so much strength and ability that he could no longer do any kind of safe transfer.
Our friend found the IBIS wheelchair to car lift online and we decided to take the risk. It was worth every penny and more. Within a day of its arrival we were mobile and in and out of the car again. It is very manageable for me to operate and in our 60’s we are grateful for anything that lightens our load.
Everything arrived as advertised. Customer service was outstanding with clear communication. I was provided help to ensure my measurements were correct and was offered a few options to customize the sling. We had to get a new car right after we bought the lift and it was a good fit in the new car.
We are very pleased and highly recommend this product.
Fantastic experience with Mediriser! We purchased a red light therapy bed and an HBOT machine. The customer service team was incredibly responsive throughout the entire process. Even when we hit a few unexpected bumps, they completely took ownership and went above and beyond to resolve them. Highly recommended for wellness equipment!
I am an executive at a large technology company, and represent a major lifestyle society with over 400 members as its president. My passion is lifestyle, and I have spent considerable time and resources testing and reviewing a number of therapies from a large number of suppliers. Allow me to say that the experience I have had so far with this company and product has been beyond exceptional. First, the customer care I have received is second to none. The team has been highly responsive no matter the day and time, provided accurate and sincere information, and given me the feeling of being looked after. I have not experienced this level of customer care before, and I would like to highlight that it is exemplary and I am ultimately grateful for this. Secondly, the product is of high quality and works better than expected. I have become an avid fan of HBOT therapy since I have received your product and would wholeheartedly recommend this therapy and your company to anybody. Lastly, what your company is doing for people is exceptional as it enables the wider public to have a revolutionary therapy at a highly affordable rate at home. Thank you for your time, effort and contribution to society. Please continue this great mission! Best regards.
Clinical excellence in a home setting. The UltraCare XT handles everything my wife's complex care protocol requires. The range of adjustment is excellent and the motor system is quiet and smooth. Her nursing team commented that having proper clinical equipment at home has made a genuine difference in her care quality. Mediriser was professional throughout.
